Intel 5 Series Digital Display Interface for HDMI

1,360 Views

Hi,

I have a big design problem...LVDS and HDMI can't show image in dual mode(both Clone and Twin fail).

In my Calpella platform(Arrandale+PCH), PortB and PortC are used to act as LVDS and HDMI.

PortB connect to a scaler then transfer to LVDS.

PortC connect to HDMI thru a level shifter.

PCH EDS says it support multiple display.

Do I use wrong ports combination? Should I change to PortB&PortD or PortC&PortD?

Is there anything to pay attention when configuring VBIOS?

Please help me..thanks.
